DISENGAGING HOOK, LINK, CHAIN, SLING, BUCKET, ANDNSKEP.

SPECIFICATION forming part of Letters Patent No. 250,779, dated December13, 1881. Application filed August 15, 1881. I (No model.) Patented inEngland December 22, 1880.

To all whom it may concern:

Be it known that I, JAMES BROWN, a subject of the Queen of GreatBritain, a resident of the city of Liverpool,in the county of Lancaster,in that part of the United Kingdom of Great Britain and Ireland calledEngland, have invented a certain new and useful Disengaging Hook, Link,Chain, Sling, Bucket, and Skep, (for which I have obtained a patent inGreat Britain, hearing date the 22d day of December, 1880, No. 5,370 5)and I do hereby declare that the following is a full, clear, and exactdescription of the invention, sufficient to enable others skilled in theart to which it appertains to make and use the same, reference being hadto the three sheets of drawings making a part of this specification.

My invention consists, essentially, of the novel combination of hook,link, chain, and sling illustrated at Figure 1; and Figs. 2, 3, 4, 5, 6,7, 8, 9, and 10 show various examples of its application.

Referring to the drawings, A is the hook; B, the link; 0, the chain, andD the sling. It will be seen that the hook A is attached to the link B,and has connected to its shank end the pendent chain 0. The hook A isprovided with a stop, a, to prevent the hook being turned the wrong wayround through the link B. The end of the pendent chain 0 is suppliedwith a hook, E, with an eye in its bend at F. The length of chain D,with the ring H and the cup J at one end and the hook K with the eye Lat the other end,forms the sling.

In the practice of my invention the link B with the tumbling-hook A ishooked over or suspended from the hook or chain of the crane or otherhoisting or lowering apparatus to which it is applied. For example, itis passed over the hook M, as shown at Figs. 2, 3, 4, 5, 6, 7, 8, 9, and10 of the drawings. The sling D is passed round the article or articlesto be lowered, and the hook K of the sling D is hooked round thesling-chain, forming a running noose. The ring H on the sling-chain isthen hooked onto the tumbling-hook A, and the hook E on the pendentchain 0 is hooked through the noose of the sling or into the eye L onthe hook K. The action is, for example,

(reference to Figs. 2 and3 The sling D being filled with a bundle ofpig-iron, N, the tumbling-hook A being attached to the sling, andlikewise the pendent chain 0 being hooked through the sling, in mannershown at Fig. 2, the bundle N is raised and lowered. The instant thelowering action is arrested, and the bundle is deposited on the groundor other receiver, the tumbling-hook Aautomaticallydisengages itselffrom the ring H of the sling D, and upon the hoisting or hauling of thecranechain the sling D is automaticallydisengaged from the bundle.through the running noose the gear, when disengaging, takes the positionshown at Fig. 3. When the hook E is passed through the eye L the slingentirely disengages and the sling is brought up on end.

Where it is-desired to weigh pig-iron or like articles the sling D,through its cup J and hook K, keeps the bundle together during theweighing operation, after which it can be again lifted, discharged, andtipped by attaching the hook K to any convenient part of the sling D.

For lifting and disengaging bales and the like the bale is slung asillustrated at Fig. 4., and is lowered onto some article, so that it isslightly raised at one or both ends to allow of thesling-chain D, or theordinary rope-sling illustrated, being drawn from under.

Figs. 5, 6, and 7 illustrate the application of my invention to bucketsor tubs. Fig. 5 illustrates raising or lowering. Fig. 6 illustratesdischarging. Fig. 7 illustrates returning empty. In this case, byplacing the studs P and S on the tub B, and attaching to the studs P thesling D, it will be seen that the tub R forms part of the sling D.

The operation will be clearly understood upon reference to Figs. 5, 6,and 7.

Figs. 8 and 9 illustrate my invention as used with skeps or scoop-tubs.Fig. 8 illustrates raising or lowering, and Fig. 9 illustratesdischarging. In this case the tub R forms its own sling, and the pendentchain 0 is preferably hooked onto the hook M, as shown.

My invention is particularly applicable for taking in and dischargingcargo on board ship, and has this further utility that when the ship isat sea the tumbling-hooks A can be applied When the hook E is passedindependently as a boat-lowering apparatus, in the manner shown at Fig.10. In this case I fit the ends of the boat with the sheaves T, and Ipass a length of rope, U, through these sheaves. This ropeU has an eye,W, at each end, which takes over the tumbling-hook A, as shown.

In operation when the boat is water-borne the hook-A automatically(lisengages, and the boat is liberated.

Having now described my invention and shown the operation thereof, Iclaim- The combined disengaging hook, link, chain, sling, bucket, andshop, and the methods of operating the same, herein set forth, and shown1 5 in the drawings hereto annexed.

In witness whereof I, the said J AMES BROWN, have hereunto set my handthis 5th day of July, in the year of our Lord 1881.

JAMES BROWN.
